This invention relates to the problemof elimi-= nating draft through the crevices around the edges of a closed door, casement window", hatch,

fahlight or the like, (all hereinafter, for brevity-,-= referred to'generically as doors), and' hasforits object to providea simple and inexpensive form of means for meeting this difficulty; more especially a form of such means which can be :sold to the user at a low price and fitted by any 1 s strip is applied to'theijanibdintelhor equivalent" means for eliminating draft through a crevice between the ordinary unskilled person. ,PAccording to the present invention,

edge or margin of a closed door and'the opposed face of the door jamb, lintel, sill orequivalent part of the door frame, comprises a: strip of material longitudinally folded over once upon itself for positioning in the "crevice'in attachment t6l-the said edge of the dooror to thesaid face" of the door frame with its folds disposed sub stantially in the flat, face to face, with the outer edges towards the direction from which'the' draft? would come into the crevice, the strip being com posed of substantially air-proof material of sufli-.

with the draft attempting to course therethrough and thereby to stop the draft, thefree fold of the strip being blowninto sealing contact, with: I u 7 transparent*cellophaneor'nlike; film materialri the adjacent face of the crevice. a

otherwise pass through the crevioeand-form a draft becomes caught as in a pocket between the two folds of the strip. It is important, therefore, that the edge of the outer fold of the strip that is to say, the fold which is not connected to 'the door, or to the door jamb, lintel or the like, as the case may be, shall be quite freewhen the door is closed and capable by ballooning of intercepting any current of airs attempting to course through the crevice and to. form a draft therethrough on the inside of the door. I n, this connection, it will be appreciatedthat. an'jadef vantage of the present invention, as distinguished; from known weather stripsv consistingfof a" strip of, felt or the like folded over,upon.i.itse nd occupying a snug fit in the crevice, isthat'the strip of the present invention,operatingas itf does to seal the crevice by ballooning as aniair pocket therein, is applicable to crevices .of widely varying widths, which of course 'the known weather strips referred to are not, depending as they do for their sealing action upon a snug rfit in the crevice.
